1 Claim.

The present invention relates to new and useful improvements in canpunches to provide a pouring opening therein.

An important object of the invention is to provide a can punch which maybe moved to any desired punchin position on a can for punching one ormore openings therein.

Another object is to provide a novel supporting base and guide means fora can perforating plunger and wherein the guide means forms a shield forthe piercing point of the plunger.

A further object is to provide a device of this character of simple andpractical construction, which is efficient and reliable in operation,strong and durable, relatively inexpensive to manufacture and otherwisewell adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebein had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a perspective view;

Figure 2 is a vertical sectional view taken on a line 2-2 of Figure 1;

Figure 3 is an enlarged sectional view taken on a line 3-3 of Figure 2;

Figure 4 is an enlarged longitudinal sectional view of the piercingpoint of the plunger; and

Figure 5 is an enlarged fragmentary perspective view of a modifiedplunger construction.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of my invention,the numeral 4 designates a base of semi-circular or half-ringconstruction having an opening 5 at its central portion and from therear edge of the base a strap metal guide 6 rises, and which includes alower upstanding le I and upper and lower horizontal arms 8 and 9connected by a vertical web positioned forwardly of leg 1.

Arms 8 and 9 are formed with guide openings ll slidably receiving aplunger l2 having a flat head l3 secured at its upper end. A coil spring14 is placed on the plunger between upper arm 8 and head l3 to hold theplunger upwardly and stop lugs l are formed on the sides of the plungerunder upper arm 8 to limit raising movement of the plunger.

The plunger is solid with a hollow lower end I6 which is beveled on acurve, as shown at H, to form a piercing point [8.

Figure 5 illustrates a plunger [9 having a hollow head 20 at its lowerend which is also beveled to form a piercing point 2|, the head strikinglower arm 9 of the guide to form a stop for the upward or retractingmovement of the plunger.

In the operation of the device, the base 4 is placed in a desiredposition, on a can 22 and plunger I2 depressed to force piercing pointI8 downwardly through opening 5 of the base into the can to punch thecan.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A can punch comprising a fiat half-ring base adapted for resting on topof a can adjacent the edge of the can, said base having end portionspositioned substantially at diametrically opposite side edges of the cantop and adapted to be held on the can by the hand of a person placedtransversely on top of the end portions of the base and on the can, astrap metal guide rising from the base at a point substantially midwaybetween the ends of the base and including a leg, upper and lowerhorizontal arms supported by the leg and a vertical web rigidlyconnecting the arms to each other, said base having a pilot openingunder the lowermost horizontal arm and said arms having openings alignedwith the pilot opening of the base, a can piercing plunger slidable insaid openings, and spring means holding the plunger in a raised positionwith its lower end shielded under the lower arm.
